[AMD] Rewrite transpose ops in pipeliner to mutable memory

[AlexAUT]

add_optimize_dot_operands may introduce a immutable shared buffer for transposed dot operands. Our stream-pipeliner then replaces the immutable buffer with a mutable buffer to be able to reuse it across iterations (pre-fetching). This will then produce incorrect transOps because the input is mutable but the result is immutable.
This PR rewrites those transOps to output a mutable layout.

Complete the following tasks before sending your PR, and replace [ ] with
[x] to indicate you have done them.

• I am not making a trivial change, such as fixing a typo in a comment.

• I have written a PR description following these
  rules.

• I have run pre-commit run --from-ref origin/main --to-ref HEAD.

• Select one of the following.

  • I have added tests.
    • /test for lit tests
    • /unittest for C++ tests
    • /python/test for end-to-end tests
  • This PR does not need a test because ``.

• Select one of the following.

  • I have not added any lit tests.
  • The lit tests I have added follow these best practices,
    including the "tests should be minimal" section. (Usually running Python code
    and using the instructions it generates is not minimal.)

Can we add a lit test for it?
